James Gibson proposed the theory of affordances to explain the human tendency to perceive the environment in terms of oneís ability to act on the world. Affordances are properties of objects that are perceived in relation to an agentís capacity for action, and tools are a special class of objects that afford both grasping and manipulation. James Gibson believed that the temporary attachment of these portable objects to oneís body extends oneís capacity for perception and action, and blurs the boundary between body and environment (1986).
Are tools incorporated into our body, or are they temporary extensions of our body? Does it depend on the type of tool? Or does it depend on the skill of the wielder?
